Try disabling the price slider widget and see if that speeds up the loading time.
If not, switch to another theme and see if the speed improves. This is just in case the widget doesn’t play well with your theme.
I’ve tried many options, even from you. Load behavior has changed when I turned off the XO10 – WooCommerce Categories widget
Problem only SET- Look – Effects – PLAIN ACCORDION
That’s very strange.
The Plain Accordion functions similarly to the Sexy Accordion but should actually be faster because it uses less CSS.
From the example web site you gave, the problem seems more to do with the size of the images.
If the problem you are facing is on another site, then maybe turn off the category images in the widget and see if it helps.
I Have
4 categories
1 cat have cca 24 sub categories and 6 sub – sub categories…
Pluging after refresh website roll all categories and sub categories next time close subcategories. Therefore it takes time especially on mobile and tablets

THANKS FOR HELP
I’m not sure if it has something to do with the Javascript library being used by the plugin.
I have already notified the Javascript author but I still haven’t got back an answer after more than a month. So I may consider changing to another Javascript library for the next release which would depend on when next WooCommerce is released.
